Produkt sehr gut. Lieferung massiv verschlechtert
Die Produkte sind so gut wie immer. Nehme sie gerne und auch seit Jahren schon. Wenns heiß ist während und auch nach dem Sport. Was sich wesentlich verschlechtert hat, ist die Lieferung. Vor ein paar Jahren noch, kamen die Lieferung teilweise schon am nächsten Tag. Mittlerweile muss ich teilweise eine Woche warten bis ich überhaupt Info vom Lieferant bekomme. Sehr schade, dass sich dieser Service derart verschlechtert hat.

Great products and really helpful advice!
Love the products and advice from Precision, it's made my marathon fuelling and hydration plan clear and easy to follow in training. I've had no issues tolerating the products during training either. Would definitely recommend!

Very impressed with precision products!
Precision products have been amazing on my training runs for a trail ultra. They have just the right amount of flavour without being too sweet and easily digested.

Fantastic fuel
I was looking for a fuel plan for my marathon coming up in June. On using the products for my long run session it was amazing how easy my body coped with the gels and chews. (90 grams/hr) would highly recommend and will use going forward for my sessions.

Great product and excellent customer service
I have found these electrolyte tabs to be excellent. They dissolve quickly and easily, leaving a pleasant lightly flavoured drink that really quenches the thirst. They also mix well with an energy powder of your choice. Would highly recommend them, particularly as they come in a variety of dosages.
On top of this, the service I have received from Precision Fuel & Hydration has been absolutely superb. From the speedy delivery, insightful articles and advice, to the follow up on purchases. Will ...

The best in the business
I was recommended Precision Fuel & Hydration by multiple people, and they have surpassed all expectations. There is no mystery as to why their name precedes them (especially amongst athletes).
